I have to agree with a t5HO being better than a CFL...
I only skimmed your post, but i think those cool night temps would be fine for highlanders if you could provide heat for the day. If they are always cool they won't do well, but give them a temp rise in the day and they'll thrive. You'd be surprised how much heat can build up from lights over the course of day, especially if you are able to close the door to the room they are in some sort of enclosure. Even with several t8 fixtures I build up a lot of heat in the room I grow my highlanders in. Best of luck!
again, at a cheaper price.
So a T5 still gives off more light/intensity ? I was looking at the lumens of the 250W bulbs and they say 12 500 each, so 25 000 in a two bulb system, as opposed to a 4 bulbed T5 unit, which has 16 500 lumens. This sounds better- but could this not transfer into reality, due to bocking, as you said? T5s may still be better... How useful are lumen outputs in deciding which is best? Can they be affected by bulb shape- thereby making the lumen reading only add up if the CFL was unravelled and then tested? Sorry for the complete lack of rational thought on this one, but I have little understanding of the terms used- to be cynical I'm sure companies do it on purpose!
